1. an image which is 1/2cm high is put 20cm infront of a convex lens which has a 10cm focal length1) draw the image formation2) write down the nature of the image
Jawaban:
the nature of the image
- not real
- upright
- enlarged
Penjelasan:
s' = -20 cm
h' = -1/2 cm
f = 10 cm
distance of object
1/f = 1/s + 1/s'
1/10 = 1/s - 1/20
1/s = 3/20
s = 20/3 = 6,67
Magnification
M = |s'/s| = |-20/(20/3)|
M = 3
object's height
M = |h'/h|
3 = (1/2)/h
h = 1/6 cm
the nature of the image
- not real
- upright
- enlarged

6. 11 A rectangle has sides which differ in length by 3 cm. If the area of the rectangle is 154 cm, find its perimeter.
Jangan dihapus.
l = length
is 3 cm longer than the w = width
Therefore
l = 3 + w
Area (a) = 154 cm²
--------------------------
Therefore
a = l · w
a = (3+w )·w
154 = w(3+w)
154 = 3w + w²
w² + 3w - 154 = 0
(w+14)(w-11) = 0
w ≠ -14
Therefore
w = 11 cm
---------------------------
Find the length (l)
l = 3 + w
l = 3 + 11
l = 14 cm
---------------------------
Find the perimeter
P = 2(l+w)
P = 2(14+11)
P = 2(25) = 50 cm
Perimeter = 50 cm

17. 10. The diagram shows a rectangle EFGH drawn inside another rectangle ABCD, such that AF = 3 cm, AE=4 cm, BG: BC = 3:5. Given that triangles AEF and BFG are similar, find the area of rectangle EFGH.
Luas area persegi panjang EFGH adalah 50 cm². Hasil ini didapat dengan menggunakan rumus kesebangunan dan phytagoras.
Penjelasan dan Langkah-Langkah:
Kesebangunan adalah ddua bangun datar atau lebih dengan perbandingan sisi yang senilai dan sudut-sudut yang bersesuaian. Tidak perlu ukurannya sama, tetapi sisi-sisi yang bersesuaian sebanding (proportional) dan sudut-sudut yang bersesuaian sama besar.
Diketahui:
AF = 3cm
AE = 4 cm
BG:BC = 3:5
ΔAEF = ΔBFG
Ditanya:
Area of rectangle EFGH atau Luas persegi panjang AFGH?
Pembahasan:
Pertama, kita cari dahulu panjang BGgunakan persamaan BG:BC = 3:5
kita tahu bahwa panjang CG= panjang AE yaitu 4 cm
sehingga akan mucul persamaan:
BG:BC--> [tex]\frac{BG}{BG+4}[/tex] [tex]= \frac{3}{5}[/tex] (kali silang)
5×BG = 3×(BG+4)
5BG = 3BG + 12 (pindah ruas)
5BG-3BG = 12
2BG = 12
BG = [tex]\frac{12}{2}[/tex] = 6 cm
Kedua, karena ΔAEF = ΔBFG (sebangun) maka kita dapat membuat persamaan kedua:AE = BF
AF = BG
EF = FG
mencari panjang BF = [tex]\frac{AE}{AF} =\frac{BF}{BG}[/tex]
[tex]\frac{4}{3} =\frac{BF}{6} \\BF = \frac{4}{3}[/tex]×[tex]6[/tex]
[tex]BF = 8[/tex] cm
mencari panjang EF dan FG menggunakan rumus phytagoras [tex]c^2 = a^2+b^2[/tex]
[tex]FG =\sqrt{BF^2+BG^2}\\FG = \sqrt{8^2+6^2}\\FG= \sqrt{64+36}\\FG=\sqrt{100}\\FG= 10[/tex] dan [tex]EF =\sqrt{AE^2+AF^2}\\EF= \sqrt{4^2+3^2}\\EF= \sqrt{16+9}\\EF=\sqrt{25}\\EF=5[/tex]
Ketiga, mencari luas area persegi panjang EFGHkarena telah diketahui bahwa panjang sisi FG = 10 cm dan sisi EF = 5 cm
Maka luas EFGH = [tex]p[/tex]×[tex]l[/tex] = 10 cm × 5 cm = 50 cm²
Sehingga luas EFGH adalah 50 cm²
